Kim four shots clear after three rounds at Wyndham

GREENSBORO, North Carolina (Reuters) - South Korean Kim Si-woo was focused intensely on his own task, birdying the final hole as he turned a narrow advantage into a four-shot lead after the third round at the Wyndham Championship on Saturday.

Kim was almost flawless, carding a six-under-par 64 to move within sight of his first PGA Tour victory.

It was a grand day for South Korean golf as compatriot Park In-bee won Olympic golf gold earlier in the day, but Kim did not draw inspiration from Park's achievement.

Indeed, the single-minded Kim was not even aware of the final round in Rio.
